Hi again,
I'm guessing that the following might also have something to do with the issue you explained because the error is similar:
With the mod Power Overload, when placing the mod custom item "Transformer", the game crashes with this error message:
The mod Power Overload (1.1.4) caused a non-recoverable error.
Please report this error to the mod author.
Error while running event PowerOverload::on_built_entity (ID 6)
The mod Water As A Resource (0.8.0) caused a non-recoverable error.
Please report this error to the mod author.
